383stroker
New member
ok... I've seen a few posts elsewhere but still can't find the answer to the question that everyone keeps side-stepping. Are there any external markings, heater hose connection, inlet clocking or anything else that would help identify a chevy water pump? I have a '91 s-10 w/383 stroker with an over-heating problem... '74 350 block (originally), '86 tpi intake and belt set-up, new 180F t-stat, '86 vette radiator (oem), electric fans and thermo switch. When I built this engine I had a few water pumps lying around and didn't realize there where more than just length differences and therefore am unsure which one I ended up with, it runs at about 230-240F after 10-15 min no matter the amb temp. Thanks for any help
